Recording material and method for producing printed matter

Technical field

The present invention relates to a recording material and a method for producing a printed material using the recording material.

Background art

[0002] Generally, image recording bodies such as credit cards and ID cards have been manufactured by silk printing, a combination of offset printing and photographs. In recent years, the image recording material has come to be manufactured simply and in a short delivery time by sublimation printing on a polyvinyl chloride resinous resin (hereinafter sometimes referred to as “PVC”) substrate or the like. It was. For example, Patent Document 1 discloses a card in which sublimation printing is performed on a receiving layer that also has a polysalt bulb isotropic force and a cured layer of an ultraviolet curable resin composition is formed on the surface layer.

Patent Document 1: Japanese Patent Laid-Open No. 07-032774

Disclosure of the invention

Problems to be solved by the invention

[0003] However, the sublimation printing method requires expensive production equipment, and the scratch resistance of the printed surface is weak so that the surface needs to be protected. In recent years, from the viewpoint of environmental protection, the substrate used for cards has also changed its PVC strength to polyethylene terephthalate-based resin (hereinafter sometimes referred to as “PET”). PET substrates are difficult to sublimate and are currently capable of printing as high quality as PVC substrates.

[0004] In addition, a method of adhering a printed matter to a card after printing by an ink jet method is also conceivable, but adhesion via an adhesive or the like is necessary, and the printed matter conforming to the card shape is also required. A cutting step is required. Furthermore, a layer that protects the surface is necessary if it is assumed to be used in the distribution stage. Therefore, when the ink jet method is adopted, the conventional technique requires a complicated process, and the recording material satisfying in terms of productivity has not been obtained.

[0005] Therefore, the present invention enables easy and production of a recording material that is capable of high-quality printing even when ink jet printing or the like is used, and has excellent scratch resistance, and printed matter using the same. It is an object of the present invention to provide a method for producing high-quality rice cake.

Means for solving the problem

[0006] Hereinafter, the present invention will be described. In order to facilitate understanding of the present invention, reference numerals in the attached drawings are appended in parentheses, but the present invention is not limited to the illustrated form.

[0007] The first aspect of the present invention comprises a support (3), a plastic layer (2) and an ink receiving layer (1) laminated in order on the support (3), and the support (3) The recording material (10) is configured to be peelable from the plastic layer (2).

[0008] According to the present invention, the ink receiving layer (1) is formed on the outermost layer of the recording material (10) composed of the support (3), the plastic layer (2), and the ink receiving layer (1). Exists. Since the ink receiving layer particularly adsorbs ink well, a clear image can be obtained by recording with ink on the surface of the ink receiving layer (1).

[0009] In the recording material (10) of the present invention, the adhesive strength A between the support (3) and the plastic layer (2) is such that the plastic layer (2) and the ink receiving layer (1). Is smaller than the adhesive strength B between (adhesive strength A <adhesive strength B). Therefore, only the support (3) can be easily peeled off from the recording material (10) or from the printed material (100) in which the recording material (10) is fused to the substrate (4).

[0010] Since the recording material (10) has a plastic layer (2) between the ink receiving layer (1) and the support (3), the recording material (10) force support ( After the 3) is peeled off, the plastic layer (2) functions as a surface protective layer of the ink receiving layer (1) which is a recording layer, and it is possible to obtain scratch resistance and further tamper resistance.

In the first aspect of the present invention, the melting point of the resin constituting the ink receiving layer (1) is preferably 40 ° C. or higher and 100 ° C. or lower. In this configuration, since the resin constituting the ink receiving layer (1) has a low melting point, the adhesive is applied by superposing the substrate (4) on the surface of the ink receiving layer (1), which is also the recording surface, and applying heat. The recording material can be easily fused to the substrate (4) without using it.

In the first aspect of the present invention, the thickness of the laminated portion (5) of the plastic layer (2) and the ink receiving layer (1) is preferably 25 μm or less. [0013] In this configuration, since the laminated part (5) of the plastic layer (2) and the ink receiving layer (1) is very thin, the substrate (4) is placed on the ink receiving layer (1) side of the recording material (10). When the ink receiving layer (1) and the plastic layer (2) are peeled off from the support (3) side, these layers (ink receiving layer and plastic layer) are separated from the substrate (4). It becomes easy to cut along the shape.

[0014] Further, even if the plastic layer (2) and the ink receiving layer (1) are to be peeled off, the laminated part (5) formed by both layers is only 25 m in thickness. It is practically difficult. Even if the temperature is raised to weaken the adhesive strength and try to break the layers, the laminated part (5) is thin and thin, so the layers expand and contract by heating and cooling during peeling. Therefore, image reproducibility cannot be obtained. By virtue of this, the effect of preventing tampering of the laminated portion (5) of the plastic layer (2) and the ink receiving layer (1) can be enhanced.

[0015] In the first aspect of the present invention, the plastic layer (2) is a single resin selected from the group consisting of polymethyl methacrylate, polymethyl acrylate, polystyrene, polycarbonate, and polyethylene terephthalate, or two or more kinds thereof. It is preferably formed from blended resin or UV-cured resin. In the following, polymethyl methacrylate may be abbreviated as PMMA, polymethyl acrylate as PMA, polystyrene as PS, polycarbonate as PC, and polyethylene terephthalate as PET.

[0016] In this configuration, the recording material (10) force can also increase the transparency of the plastic layer (2) that functions as a surface protective layer after the support (3) is peeled off. The image of the ink receiving layer (1), which is the recording surface underneath, can be easily seen. These resin materials have relatively high hardness and can enhance the function as a surface protective layer. Further, when the support layer (3) is made of polyethylene (hereinafter sometimes referred to as “PE”), polypropylene (hereinafter sometimes referred to as “PP”), etc., it can be easily peeled off.

[0017] In the first invention, the plastic layer (2) is preferably formed of PMMA.

[0018] In this configuration, since PMMA has both relatively high hardness and easy cracking, when the support (3) side force is also peeled from the ink receiving layer (1) and the plastic layer (2), These layers (ink receiving layer and plastic layer) can be cut along the shape of the substrate (4). Easy layering.

[0019] In the first aspect of the present invention, the plastic layer (2) contains an inorganic filler or organic fine particles (21) in an amount of 2 parts by mass or more based on the total mass of the plastic layer (2) (100 parts by mass). It is preferable that 50 parts by mass or less is added.

[0020] With this configuration, the plastic layer (2) can be added with inorganic fillers or organic fine particles (21) to reduce the flexibility of the plastic layer (2) and to form many fracture points. It becomes easy. By force, after the substrate (4) is fused to the recording material (10), the plastic layer (2) can be easily cut along the shape of the substrate (4). Further, if the plastic layer (2) is cut into a predetermined shape, the ink receiving layer (1) laminated and integrated with the plastic layer (2) can be easily cut in the same shape.

[0021] The inorganic filler (21) added to the plastic layer (2) is preferably silica. In this configuration, the silica used as the inorganic filler is transparent, and the image printed on the ink receiving layer can be observed in a clear state through the plastic layer as the surface protective layer.

In the first aspect of the present invention, the ink receiving layer (1) is preferably formed using a resin represented by the following general formula (1) as a main component.

[0023] [Chemical 1]

[0026] In the general formula (2), Z is a hydrocarbon group having 1 or more carbon atoms, a, b and c are each an integer of 1 or more, and the weight ratio calculated from a, b and c , {44 (a + c) Z (molecular weight of oc-refinoxide having 3 or more carbon atoms) X b} is 80Z20 or more and 94Z6 or less. [0027] The above "main component" means that the resin represented by the general formula (1) is preferably 50% by mass or more based on the mass (100% by mass) of the entire ink receiving layer (1). , More preferably 90% by mass or more, still more preferably 98% by mass or more.

[0028] In this configuration, the ink receiving layer formed using the resin of the general formula (1) as a main component

(1): When PET is used as the substrate (4), heat fusion with the substrate (4) is easy.

. In addition, the ink receiving layer (1) of this configuration can be easily formed into a film having a thickness of several microns, and in combination with the plastic layer (2) formed to have a comparable thickness, It is possible to obtain a recording material having tamper resistance and easy cutting along the substrate shape.

In the first invention, the printing method on the ink receiving layer (1) is not particularly limited as long as it does not affect the ink receiving layer (1). Examples of the printing method include an inkjet method, a thermal transfer method, a laser exposure thermal development transfer method, and an electronic photo method using a laser or LED. Among these, as a printing method for the ink receiving layer (1), it is preferable to employ an ink jet method. In this case, a high-quality image can be obtained at low cost on the recording material (10).

[0030] The second aspect of the present invention includes a step of forming a printing surface on the ink receiving layer (1) of the recording material (10) of the first aspect of the present invention, and bonding a substrate (4) having a predetermined shape to the printing surface. And the step of destroying the plastic layer (2) along the predetermined shape of the substrate, the substrate (4), the ink receiving layer (1) and the plastic layer

If so, it is not particularly limited. Specific examples of materials used for the support 3 include polyethylene (PE), polypropylene (PP), ethylene vinyl acetate copolymer (EVA), releasable polyethylene terephthalate, acid-modified polyolefin, syndiotactic polystyrene, and the like. Resin. As the releasable polyethylene terephthalate, a polyethylene terephthalate sheet having releasability imparted to the surface by silicone coating or fluorine processing can be used.

[0036] Since these resins have flexibility, they can be folded and wound on a roll or the like when peeling from the adjacent plastic layer 2, and the peeling process is simple and easy. Can be. Among these materials, polyethylene (PE) or polypropylene (PP) is preferably used from the viewpoints of releasability, material cost, and availability, and acid-modified polyolefin is preferably used from the viewpoint of adhesive strength control. . [0037] In addition, the lower limit of the thickness of the support 3 is preferably 30 µm or more, more preferably 50 µm or more, and the upper limit is preferably 250 µm or less, more preferably 100 µm or less. . If the thickness of the support 3 is too thin, the predetermined rigidity cannot be maintained, and stagnation occurs in the manufacturing process, and the printed image is stretched in the length direction due to the winding tension of a roll or the like. It may be distorted and is not preferable. In addition, if the thickness of the support 3 is too thick, it is not preferable because it unnecessarily becomes bulky when coiled on a roll.

[0038] <Plastic layer 2>

The physical properties required of the resin used in the plastic layer 2 are that it must function as a surface protective layer when the support layer 3 is also peeled off later, so that the hardness and melting point above a predetermined value are required.

By forming a break point in the layer 2, it becomes easy to make the shape of the plastic layer 2 transferred to the substrate 4 side conform to the outer shape of the substrate 4.

[0042] If the content of the inorganic filler or the organic fine particles 21 is too small, the filling effect cannot be obtained. On the other hand, if the content of the inorganic filler or the organic fine particles 21 is too large, the mechanical properties of the plastic layer 2 become fragile and it becomes difficult to sufficiently perform the function as the surface protective layer.

These may be used alone or in admixture of two or more. In addition, polyacetic acid bull (PVA), polybyl pyrrolidone (PVP), etc. can be blended and used within the range that can maintain the adhesive strength during fusion.

[0045] When the main component is capable of maintaining the adhesive strength, the viewpoint component is preferably 50% by mass or more based on the total mass of the ink receiving layer (1) (100% by mass). It is preferably 90% by mass or more, more preferably 98% by mass or more.

The resin used for the ink receiving layer 1 needs to have a melting point of 100 ° C. or lower so that the ink receiving layer 1 can be easily heat-sealed to the substrate 4. In addition, when using In consideration of the heat resistance of the ink receiving layer 1 and image storage stability, the melting point is preferably 40 ° C. or higher.

[0047] The main component of the resin constituting the ink receiving layer 1 is preferably a water-absorbent resin that can be formed into a film by a dry method such as an extrusion method with excellent productivity. For example, polyethylene oxide is suitable as the resin. In the present invention, it is preferable to use a hydrophilic thermoplastic resin composed of a repeating unit represented by the following general formula (1) as a main component constituting the ink receiving layer 1. .

[0057] <Optional components added to each layer>

The recording material 10 of the present invention may contain a cationic polymer for the purpose of improving ink bleeding characteristics and fixing properties. Cationic polymer is added The layer is not particularly limited, and can be contained in one or both of the ink receiving layer 1 and the plastic layer 2. Examples of the cationic polymer preferably used in the recording material 10 of the present invention include polymer compounds such as polyallylamine hydrochloride, polyalkylamino acrylate, and the like, such as a copolymer having a quaternized amino group and having a monomer power.

Various additives such as an antioxidant and an ultraviolet ray inhibitor are added to the ink receiving layer 1 and the plastic layer 2 within the range. Further, it can be contained. For example, in order to prevent thermal deterioration during melt extrusion, an antioxidant can be contained in the greave composition. The amount of the anti-oxidation agent added for improving the thermal stability is suitably about 0.3 to 1.5% by mass based on the mass of the whole layer to which it is added (100% by mass). It is.

The thickness of the laminated portion 5 of the ink receiving layer 1 and the plastic layer 2 of the present invention is preferably 25 m or less, more preferably 20 m or less, and even more preferably 15 m or less. Furthermore, it is most preferable that it is 12 m or less. In addition, the lower limit of the thickness of the ink receiving layer 1 is preferably 5 μm or more, and the upper limit is preferably 14 μm or less, more preferably 10 μm or less.

If the plastic layer 2 is too thick, it is difficult to cut along the shape of the force substrate 4, which is not preferable.

[0064] Further, it is not preferable that the total thickness of the ink receiving layer 1 and the plastic layer 2 exceeds 25 μm, since the fracture strength of the laminated portion 5 is high and the alteration is easy and the cutting is not easy. By setting the thickness of the laminated portion 5 and each layer as described above, the tamper resistance is improved and the production at the time of card manufacture becomes easy.

[0065] <Manufacturing method 1: Printed product (laminate) 100>

The recording material 10 of the present invention is produced by laminating a plastic layer 2 and an ink receiving layer 1 on a support 3. There are no particular restrictions on the lamination method. For example, when the support 3 is a resin, the resin to be the ink receiving layer 1, the resin to be the plastic layer 2, and the resin to be the support 3 are blended or necessary. The recording material 10 according to the present invention can be formed by placing the pellets in accordance with the temperature in a T-die extruder, melting and co-extrusion, and cooling and solidifying with a cooling roll, water cooling, air cooling, or the like. .

In addition, the recording material 10 is formed by directly extruding the resin to be the plastic layer 2 and the resin to be the ink receiving layer 1 onto the support 3 prepared in advance, such as a T-die. Alternatively, a film of each layer may be formed by extrusion and then laminated sequentially. When the plastic layer 2 is an ultraviolet curable resin, the ink receiving layer 1 or the support 3 formed into a film shape is coated with an ultraviolet curable resin by gravure coating or the like and irradiated with ultraviolet rays. After curing, it can be easily manufactured by laminating the remaining layers on it.

FIG. 2 shows a method for producing a printed matter (laminate) 100 using the recording material 10 of the present invention. In the recording material 10 of the present invention, an image or the like can be printed on the upper surface of the ink receiving layer 1 as shown in FIG. The printing method is not particularly limited as long as it does not affect the ink receiving layer. For example, an inkjet method, a thermal transfer method, a laser exposure Thermal development transfer method, laser or LED electrophotographic method, etc. can be adopted. In the thermal transfer method, laser exposure thermal development transfer method, and electronic photo method using laser or LED, it is desirable that the roll that contacts the ink receiving layer does not reach a high temperature. Of these, it is preferable to use water-based ink as a printing method. Furthermore, it is preferable to adopt an ink jet method.

In the recording material 10 of the present invention, after recording on the upper surface of the ink receiving layer 1, as shown in FIG. 2 (b), the substrate 4 is placed on the upper surface of the ink receiving layer 1 to perform heat fusion. It can be carried out. The substrate 4 used in the present invention is not particularly limited as long as the resin forming the ink receiving layer 1 is heat-sealed. For example, PET or biodegradable resin can be used. Examples of biodegradable resins include polyesters produced by microorganisms such as 3-hydroxybutyric acid / 3-hydroxyvaleric acid copolymer, composite resin of starch and polybulal alcohol, polylactic acid or copolymer of lactic acid and oxycarboxylic acid It is possible to use an aliphatic polyester such as a thermoplastic rosin having a main component of styrene, a poly-strength prolacton, and the like.

[0069] Further, as the substrate 4, paper, a metal plate, a ceramic plate, or the like that has been surface-treated so as to be fused can be used. Among these, as the substrate 4 in the present invention, PET is preferably used from the viewpoint that it is easy to obtain, cost, easy to process, and heat fusion to a water-absorbent resin. The size of the substrate 4 is not limited and can be freely used up to the size of a business card size that is not limited. Specific methods of heat fusion include a press method, a nip method using a hot roll, and a hot air pressure bonding method.

[0070] After applying heat fusion, by applying a stress to peel off from the recording material 10 to the substrate 4, the support layer 3 is peeled off as shown in FIG. The ink receiving layer 1 is also cracked along the shape of the substrate 4, and the ink receiving layer 1 is also cracked in the same shape, so that the ink receiving layer 1 and the plastic layer 2 fused to the substrate 4 are separated to the substrate 4 side. Through this process, a printed matter (laminated body) 100 is formed in a state in which the ink receiving layer 1 and the plastic layer 2 are sequentially laminated on the substrate 4. In the present invention, since the plastic layer 2 contains a predetermined amount of a predetermined inorganic filler or organic fine particles, the plastic layer 2 is easily cracked along the shape of the substrate 4, and the nose when the plastic layer 2 is cracked. The occurrence of waste is suppressed.

[0071] Further, the recording material 10 of the present invention is half-cut into an arbitrary shape (only the laminated portion 5 is cut and supported). When the carrier layer 3 is not cut), and the portion is heat-sealed and peeled off from the substrate 4, a printed layer and a protective layer are formed on the substrate 4 only at the portion that has been half-cut and fused. In this way, a printed matter (laminated body) 100 that can be subjected to other processes such as silk printing and magnetic tape sticking can also be created in the remaining part.

In Examples 1 to 4 of the present invention, generally good results were shown in all evaluation items. In Example 2, since the laminated portion of the ink receiving layer and the plastic layer had a certain thickness, the evaluation of tampering was slightly inferior. Further, in Examples 1, 2, and 4, since the plastic layer is made of attalinole or polystyrene, it is scratch resistant as compared with the case of using the UV effect resin in Example 3. The property was slightly inferior. In Example 3, the plastic layer did not contain an inorganic filler or the like, but the plastic layer itself has the property of being easily broken, so that no force was generated when the support was peeled off.

[0091] In Comparative Example 1, only the sublimation printing was performed on the surface of the PVC card substrate, so that the scratch resistance was inferior, and the surface could be easily altered by performing sublimation printing on the surface again. I was able to. Also, because the substrate is PVC, the environmental protection point is not desirable.

In Comparative Example 2, since the conventional inkjet media was printed, the substrate force could be easily peeled off and tampering was easy. In addition, since it is manufactured by adhering to the substrate using an adhesive, the white color of the substrate becomes dull due to the adhesive layer, and the image visibility is poor. In addition, it was difficult to position the media with adhesive applied to the substrate, and workability was poor.

[0093] In Comparative Example 3, since the ink-receiving layer is thick and the plastic layer contains no inorganic filler or organic fine particles, the plastic layer and the plastic layer and Since the ink receiving layer is difficult to break due to the shape of the card base material, nose is generated around the card and peeling occurs between the ink receiving layer and the card base material.

[0094] Although the present invention has been described above with reference to embodiments and examples that are currently considered to be the most practical and preferred, the present invention has been disclosed herein. The invention can be appropriately changed without departing from the scope or spirit of the invention that can be read from the claims and the entire specification, not limited to the embodiments and examples, and the recording material accompanied by such a change, and It should be understood that the method for producing a printed material using the method is also included in the technical scope of the present invention.
